4 Claims. (Cl. 2985) The invention aims to provide an exceptionallyterminal and the terminal post and there is simple and inexpensive, yetan easily operable therefore no danger of injuring the battery case, andeflicient tool for pulling battery terminals cells or plates. fromterminal posts or performing similar work, In the preferredconstruction, the two levers 5 5 the tool being so constructed that itsuse will cross each other and are fulcrumed together at 5 place nostrain upon the battery case, cells or their crossing point, and whenthis construction plates even though a terminal being pulled has isfollowed, the slots l must converge downbecome badly corroded, andtherefore very wardly. These slots may be slightly curved as tenaciouslyconnected with the terminal post. shown.
